Case for Buck Converter with LCD Display

thingiverse

I wanted a sturdy case for an LM2596-based buck converter I found on Amazon. There are a lot of suppliers for these, this is one I've purchased and tested with this case: https://smile.amazon.com/gp/product/B07WQJ2GD6 The model uploaded is PLA @ 0.15mm and it's a very nice print. It can be done in PETG and I have also printed it in 0.20mm fast with pretty good results. Depending on your printer and filament, you may need to print a brim around the buttons. With PLA I found this necessary, I did not need it with PETG. This uses 4 hex head M3 x 16mm screws to sandwich the board and close the case.
